feat(wave): #119/#122/#131/#132 verts + sprint plugins ESM/persistance #135/#136/#139

État d'intégration confiné à la branche batch. Les tickets #119 (skills →
capacités agent découvrables), #122 (override permissions par défaut), #131
(effort par agent/presets) et #132 (outil MCP d'édition du contexte projet)
sont verts en périmètre. Le sprint plugins multi-fichiers ESM / persistance
plugin-owned (#135/#136/#139) est co-implémenté dans les MÊMES fichiers de
câblage (frontend/src/ports/index.ts, backend/src/lib.rs, domain/ports.rs,
backend/dto.rs), inséparable sans staging interactif (indisponible ici).

Commit unique volontaire : préserve l'état vert QA sans découpe hunk risquée.
NON mergé vers develop tant que #137 (QA e2e plugins) n'est pas vert.
